Give the initial guide a thorough study once again
I are in the middle or if your friend then he is in the middle of the process
If still failed please update
try this with PIT flash over odin 3.07( https://www.dropbox.com/s/qs9wigflyr...ACTORY_XEF.rar) download and extract you will find all files inside
make sure usb drivers are installed and phone is detected
if failed, restart the System, and try again, this might fail in the middle, which means pit is flashed, you can then flash the rescue firmware without pit, which may fail few times but keep it going, it will be a success at the end ( lucky enough if went through in first try)
after flashing this rescue firmware download 4.4.2 kitkat from first post and flash that to bring it back to life( iMEI and Network) ( 4.4.2 kitkat ) https://mega.co.nz/#!2QRmCbyb!YkWs92...qHm4XIDbgLsEK0

My questions are
1-Which the rescue firmware, the 2nd file?
2-Phone was flashing a firmware and encountered the "Firmware upgrade encountered an error..." screen. Do I first flash the rescue firmware, then PIT, then reboot or PIT, then reboot see if that works?
Sorry for asking such noob questions but I am one with this phone.
